What are the specific terms for 'faith' and 'patience' that Hemadpant says are required for spiritual attainment, and what prompted this lesson?

In Chapter 2 of the Shri Sai Satcharitra, Hemadpant identifies the two essential qualities for spiritual attainment using the Marathi terms 'Shraddha' for faith and 'Saburi' for patience. He explicitly states, "Without faith (Shraddha) and patience (Saburi), Not a bit of the spiritual goal is achieved." This powerful lesson was prompted by his own personal failing. He had a tendency towards prideful debate, which his Guru, Sai, corrected with what the author calls a "speech-arrow" meant to destroy his pride. This experience taught him the futility of argumentation and the supreme importance of humility, which in turn opened his heart to the indispensable nature of Shraddha and Saburi.
